SPECIFICATION formingpart of Letters Fatent No. 738,367, dated September 8, 1903.

Application filed September 9,1902. Serial No. 122,717- (No model.) i

To aZZ whim t it may concern.-

Be it known that 1, CHARLES E. SMITH, a citizen of the United States, residing in Goffstown, in the county of I-Iillsboro and State of New Hampshire, have invented. a certain new and useful Im provement in Extension-Tables,

V of which the following is a specification.

This invention relates to extension-tables 51011 as are capable of being continued in T-ength by leaves arranged beneath the top when the table is unextended, but adapted to be placed one at each end of the top on a level therewith and to be supported by sliding elongations of the frame.

In extension-tables it is common to divide the top vertically and transversely in the middle and to connect each half of the top with an extensible part of asectional frame secured on the legs or supporting parts of the table, which frame and legs are drawn apart when the table is extended and the space between the halves of the top is filled by supplementary top sections or leaves. In other extension-tables the top is rigidly secured in the middle only to an inextensible frame, and the leaves when not required are lowered and pushed between the top and said frame. In the table herein described the top of the unextended table is in a single piece and is secured to guide-rails connecting the movable parts of the frame, and said frame may be extended to lengthen the table in either direction without moving the top proper at all.

The object of the invention is to secure simplicity and rigidity of construction, a saving of material, and a symmetrical appearance of the table, 'whether the same is unextended, partly extended, or extended to its greatest capacity.

Inv carrying out this invention the table is provided with detachable reversible leaves having slides which engage the supportingframe and'hold the leaves in operative position on alevelwith the top at the ends of M said top and which form a finish for the table when the leaves are not in use. V

In the accompanying drawings on two sheets, Figure 1 is a side elevation of a table provided with my improvement, the table being represented in full lines as unextended and in dotted lines as extended at'each end; Fig. 2, a plan of the table extended, the leaf at the left being omitted; Fig; 3, a plan of the table inverted and fully extended, one pedestal half and the inner end portion of one side arm being in horizontal cross-section and the sliding connections being indicated by dotted lines; Fig.4, an end elevation of the table with the adjacent leaf removed, the lower part of the pedestal being omitted. The following figures show slight modifications: Fig. 5 is a plan of the table extended at one end, the leaf being omitted and the top being broken away at said end to show trays supported on the slide-frames Fig. 6, a plan of the same inverted and ex tended; Fig. 7, an end View of the same.

The top A is a flat rectangular board or plate, to the bottom of which are secured two parallel guide-rails a a, which extend nearly the entire length of said top. In order to permit the expansion and contraction of the top A without buckling or cracking, the guiderails are rigidly fastened to said top only midway between their ends. This may be accomplished in any usual or convenient manner, as by glue and dowels; but I have shown screws b Figs. 2 and 3, which connect said top and guide-rails and which project down through said rails and serve as stops for the slide-frames, as hereinafter described. The end portions of the rails 01. a are held against the top by angle-clips a secured to the under side of said top and entering short grooves 01, in the inner faces of said rails, thus permitting the ends of said top to move slightly on said rails. Rectangular slide-frames B B are adapted to slide from the middle of the top A outward and to project beyond the adjacent end of said top, as shown in Figs. 2 and 3. Each slide-frame B B consists of two sides I) b, (of greater depth or vertical thickness than the guide-rails A A,) an outer end piece 19 which is let into the sides I? b flush with the bottom of the same, and an inner end b which is secured to the bottom of said sides b7) and in thickness equals the top A or a leaf 0 or O. The outer faces of the guiderails a a and the inner faces of thesides b b,

respectively, are longitudinally grooved at a and tongued at Z9 together in a wellknown manner to permit the frames B B to slide on the under side of the top. Each frame B B is provided with a long slide-arm b rigidly secured thereto, each arm 6 being arranged side byside with the other arm b and said arms being tongued at b and grooved at b together, as shown in Figs. 3 and 4, on their inner faces in such a manner as to be capable of sliding freely on each other. Said arms 12 are provided on their outer faces with grooves 79 to receive the edges of clips b", socured to the under side of the top A, said clips being shaped in such a manneras to keep said arms in engagement with each other and against the upper surface of said top. These long arms 19 keep the sides 1) 79 parallel with the guide-rails a ct and prevent them from binding thereon. Steps 6 close the inner ends of the grooves 79 and'limit the outward movement of the slide-frames B B and prevent the latter from being entirely removed from the top A. Other stops, represented as pins 5 or the ends of the screws projecting from the under sides of the guide-rails a a,

are struck by the ends 5 and prevent the slides B B from passing the middle of the top A on the inward movement of said slides.

The slide-framesB B are duplicates of each other, except that one of the arms b is grooved and the other is provided with a tongue, as above described.

The vertical supporting column or pedestal is centrally vertically divided transversely of the top A into two equal parts D D, each of which is rigidly secured to the middle of the under side of one of the ends 19 so that when the table is unextended said halves D D are close together, as shown in full lines in Fig. 1-; but when either of said slide-frames is drawn outward to extend the table, as indicated in dotted lines in Fig. 1 or in Figs. 2 and 3, the corresponding pedestal half moves with such slide-frame. The pedestal D D is of any desired symmetrical shape in horizontal cross-section, as cylindrical, rectangular, orother shape, but is represented as octagonal in horizontal cross-section. Each pedestal half is preferably provided with feet d d, of any usual or desired shape, rigidly secured thereto.

. Each leaf 0 C is a duplicate of the other and is of the same thickness as the top A and in length equals the width of said top. The combined width of a leaf and an end strip 1) is equal to one-half the length of the top A. Each leaf has rigidly secured thereto parallel sides 0 0', arranged at a suitable distance apart to admit the sides b Z) of a slideframe B B, and said slides and sides are provided with grooves c and tongues Z1 adapted to engage each other, so that the leaves may be supported by and slide on the frames B B, and said tongues and grooves are equally distant from the tops and bottoms of the slides and sides, respectively, so that a leaf may be supported on a. slide-frame (when the latter is drawn out) on a level with the top A or may be supported in an inverted position below said top, as shown in full lines in Fig. 1, when the slide-frame is not drawn out. The slides a c on each leaf are preferably long enough to reach just across'an end strip b and to meet the corresponding slides of the other half at the middle of the unextended table, as shown in full lines in Fig. 1, and the outer ends of said slides on each leaf are joined by a rail 0 of the same depth as a slide, the rails serving to give a uniform finish all around the unextended table and to stiffen the leaves and prevent their warping.

The position of the stops b and guide-plates 6 permits the end strips to be drawn out just to the ends of the top A, so that the inner face of each pedestal half is always at a distance from the adjacent end of the top surface of the table equal to the combined width of an end strip 6 and a leaf, or a distance equal to half the length of the'top proper, A, whether the table be unextended or extended at one or both ends. Suitable handles E, represented as loops attached to end strips-b may be used in drawing out the slide-frames B B.

One pedestal half, as D, may be provided With a steady-pin 01*, which projects horizontally therefrom and enters a corresponding hole (i in the other pedestal half when the table is unextended to keep the halves D D in line with each other.

In Figs. 5, 6, and 7the only difference from what is shown in the preceding figures and already described is that instead of using the loops or handles E E, I provide the end strips 19 with holes 0Z in which the fingers may be inserted to draw out the slide-frames,

and that I arrange trays F on the slide, which may be used to hold tablecloths, napkins, ping-pong balls, or other articles commonly used on or about such tables. The outer side of each tray F is grooved or rabbeted atf to allow said tray to slide under the clip (1 The same letters indicate the same parts as in the other figures;

I claim as my invention 1. The combination of a solid top, a-slideframe, movable on the under side of said top and adapted to project beyond the ends thereof, and a solid unattached leaf adapted to be supported on said frame below said top and ioO IIO
